DNS is a naming system for computers connected to internet or intranet. It stands for Domain Name System. It identifies every computer, resource or service with a unique numeric identity. It is the building block of internet and intranet.
DNS appliances management therefore becomes an important task of network administrator and it requires products that do this chore efficiently and easily.
Active Directory is dependant on DNS. Network administrators are aware of this fact. A faulty DNS or redundant DNS can spell disaster. It can result in server crashes, slow lookups and failure to access Active Directory services.
Assigning faulty DNS is one of the commonest issues.
Along with DNS and time synchronization is also important; if either of those two components is not configured properly it will only create chaos and productivity loss. Active Directory contains an Active Directory Container object for each zone or component. A non-existent dynamic DNS or an incorrect manual update often results in erroneous records not registering properly.
Another issue which is typical on this environment is shifting or de-registering of DNS records when the service or component is not required of moved to a different host. This invariably creates a ghost record which can create trouble in accessing the old domain controller and the new one will remain hidden.
A DNS appliance therefore plays an important role in efficient monitoring of all DNS records. Every big enterprise needs this keep the operation working non-stop and thereby avoiding productivity loss. It offers centralized domain and database management. It also provides other support and help such as data integrity verification, diagnostics and easy integration.
Dynamic Host Configuration Protocol or DHCP on the other hand automates naming assignment to network devices. DHCP is useful because it makes it easy to add new machines to the network.
DHCP appliances and DNS appliances are products and services that help enterprises manage complex IP networks effectively and efficiently.
DNS appliances management are dedicated security appliance that enables administrators in any organizations to manage Domain Name Services (DNS). Here are some of its salient features.
• Total DNS functionality;
• Easy migration feature along with full support of DNS.
• 128-bit SSL enabled management console for higher security.
